摘要： A tray guide mechanism for an optical disc drive guides a backward and forward movement of a tray installed to slide into and out of a housing made of a lower case and an upper case. The tray guide mechanism includes guide rails installed to slide into and out of both sides of the upper case, a guide rail supporting unit installed at both sides of the lower case, to prevent the guide rails from deviating from a backward and forward moving path, and rail combiners formed at both sides of the tray in a moving path of the tray, and combined with the guide rails to slide into the guide rails. The tray guide mechanism also includes a forward moving distance limiting unit to limit a moving distance of the tray and the guide rails in a direction to which the tray and the guide rails project to prevent the tray from detaching from the housing. The tray guide mechanism also includes vertical and horizontal restrainers to prevent vertical and horizontal movement of the tray. The guide rails are shaped such that the rail combiners are inserted thereinto, and includes rails which slide into and out of the rail combiners while remaining in contact with the rail combiners. The guide rails also include rail covers which are fixed to outer sides of the rails and slide into and out of the lower case while being in contact with the lower case. The tray guide mechanism is configured such that a guide rail is installed in contact with a rail and a rail cover, and thus is strengthened to firmly support the tray and is installed in a narrow space of the compact optical disc drive. Also, the tray guide mechanism includes the vertical and horizontal restrainers that prevent vertical and horizontal vibration or swaying of the tray.

摘要： A disc cartridge having a disc to record information and a case to accommodate the disc includes a cleaning unit installed inside the case and selectively contacting or being separated from the disc depending on a flow of air generated during a rotation of the disc, so that the cleaning unit removes foreign material adhering to a surface of the disc when contacting the disc. Since cleaning is automatically performed depending on the flow of air, inconvenient manual operation is not necessary. Furthermore, since the cleaning unit does not deviate from a disc area, miniaturization of the disc cartridge or disc recording and reproducing apparatus is possible.

摘要： A disk cartridge and a disk recording and/or reproduction apparatus including a protrusion group which is made up of a plurality of protrusions and formed within a case housing a disk or within a housing in which a disk is loaded. Accordingly, the protrusions induce the flow of air generated during the rotation of the disk to serve as a force generated by variations in flow velocity and pressure. Therefore, foreign materials can be effectively removed from the surface of the disk using the flow of air without a separate cleaning apparatus.

摘要： A tray locking apparatus of a disc drive to lock a tray on which a disc is accommodated and which is inserted into a main body of the disc drive. The tray locking apparatus includes a locking pin provided at the main body, a locking lever rotatably installed at the tray and having a hook portion at one end thereof which is caught by the locking pin as the tray is inserted into the main body, an elastic member to elastically bias the locking lever in the direction in which the hook portion is caught by the locking pin, a driving mechanism to rotate the locking lever to escape from a position where the hook portion is caught by the locking pin when the tray is drawn, and a counter impact unit installed adjacent to the locking lever and having a moment to rotate in a direction opposite to that of the locking lever, so that when the locking lever is rotated by an impact in a direction to be unlocked, the counter impact unit rotates in the opposite direction and bumps against the locking lever. Thus, when an external impact is applied, the locking state of the tray can be firmly maintained.
